Individual aquaculture farmers in developing countries play an important role in ensuring food security. This study uses survey data from aquaculture households in Rongcheng and Xiangshan cities in China to explore the impact of cooperative participation on the benefits to the aquaculture households. The empirical results show that the participation of aquaculture farmers in cooperatives has effectively increased their net profit and output per unit area. On average, participating in cooperatives increased the net profit and output per unit area of farmers by approximately 15.55% and 11.47%, respectively. The test results of the mechanism show that the information services, technical training, and product sales guidance provided by the cooperatives have increased the net profit of the farmers. At the same time, the information services and product sales guidance provided by cooperatives are important reasons for the increase in the output per unit area.

The present study aimed to explore the influence of donation amounts on donation decisions in different donation contexts and to reveal the psychological mechanisms. Furthermore, we focused on how to enhance individuals’ intention to donate voluntarily. We designed an experiment on donation decisions, employing event-related potentials (ERPs) to probe the effect of psychological mechanisms on donation decisions by detecting the neural basis of donation decision-making. Based on S-O-R (stimulus-organism-response) theory, we used donation contexts and donation amounts (stimuli) to induce psychological activity in the participants (organism) and then influence individual donation decision behaviors (response). Moreover, we applied psychological reactance (PR) theory to discuss the effect of donation context on decisions and the corresponding psychological process. The behavioral results showed that donation contexts (mandatory vs. voluntary) were significantly related to the donation amounts (i.e., less vs. more money that the charity received than money that the participants donated). At the ERP level, compared with mandatory donation, voluntary donation evoked a larger P2 amplitude when the charity received less money. In addition, a larger mean amplitude of LPP was elicited by voluntary donation compared to mandatory donation. This study provides practical implications for charity organizers to guide people to donate voluntarily.

This study focuses on the national-level green factory certification program. Drawing on panel data of Chinese A-share listed manufacturing firms from 2004 to 2024 and employing a difference-in-differences (DID) approach, it investigates the impact of green factory certification on corporate green innovation and examines the underlying mechanisms, with the aim of providing empirical support and policy insights for the green transformation of the manufacturing sector. The findings are as follows. First, inclusion in the green factory list promotes both radical and incremental green innovation. However, firms show a stronger inclination toward deepening exploration within their existing knowledge base, as evidenced by an increase in patent output. Meanwhile, knowledge recombination exhibits a certain degree of concentration. Second, green factory certification significantly stimulates green innovation in traditional industries and non-heavily polluting sectors, but has no significant effect on firms in high-technology industries or heavily polluting sectors. Third, green factory certification facilitates corporate green innovation through two channels: internal drivers and external support. On the one hand, it strengthens environmental investment and fosters green awareness; on the other hand, it expands financing channels and attracts green capital.
